1 Claim. 1

The invention relates to a rearscope for vehicular service and more especially to a rearview vision device.

The primary object of the invention is the provision of a device of this character wherein the same when installed within a vehicle or the like there can be obtained a rear vision so that an operator of such vehicle can ascertain oncoming tramc from the rear of the said vehicle and thus eliminate accidents, the device being of novel construction and is unique in the application thereof within the vehicle giving a wide range rear vision to the operator.

Another object of the invention is the provision of a device of this character, wherein adjustment thereof can be had for near or distant rear vision, the adjustment being manually effected from within the vehicle where installed.

-A further. object of the invention is the provision of a device of this character, which is simple in construction, thoroughly reliable and effective in operation, strong, durable, readily and easily adjusted, conveniently accessible, does not detract from the appearance of the vehicle where i installed, possessed of few parts, thus economical in repairs and replacements, and inexpensive to manufacture and install.

with these and other objects in view the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, which disclose the preferred embodiment of the invention, and pointed out in the claim hereunto appended.

In the accompanying drawings:

Figure 1 is a fragmentary side view of a vehicle showing the device constructed in accordance with the invention installed therein;

Figure 2 is a mutilated vertical longitudinal sectional view through the device;

Figure 3' is a horizontal sectional view taken approximately on the line 3-4 of Figure 1 looking in the direction of the arrows;

Figure 4 is a sectional view on the line 4-4 of Figure 2 looking in the direction of the arrows;

Figure 5 is a sectional view on the line 5----I of Figure 2 looking in the direction of the arrows;

Figure 6 is a detail sectional view taken on the line 8-4 of Figure '3 looking in the direction of the arrows.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawing in detail, A designates generally a portion of a motor vehicle, in

this instance of the sedan type, and within this vehicle is located the device constituting the present invention as hereinafter set forth in detail.

The invention constituting the present device, comprises front and rear overhead rotatable mirrors III, II, and I2, respectively, which are arranged within the vehicleclose to the roof area I3 thereof and inside of a tunnel formation [4 having a rear transparent glass window, located at the rear end of such vehicle A.

The mirrors I0, II and I2 are turnable on horizontal arbors I6, which are disposed crosswise of the tunnel formation I4, fore and aft thereof. The arbors It for the rear mirrors II and I2, are vertically aligned in spaced superposed relation to each other. On the arbors I6 for the front and uppermost rear mirrors I0 and I I respectively are fixed worm gears II meshing with worm pinions I8, which are fixed to a coupling shaft I9,

journaled in suitable bearings 20 thereof, so that when this shaft I9 is rotated the mirrors I0 and II will turn in unison with each other.

The arbor- I6 for the mirror I2 is fitted with a gear 2| and this with the gear II on the arbor of the mirror I I mesh with a toothed rack bar 22, which is movably supported on guides 23, so that when the mirror I I is turned the mirror I2 simultaneously turns therewith and at the same angle to the vertical, this angle also being true with respect to the front mirror III.

Arranged above the head of the operator of the vehicle A is a vertically disposed adjusting shaft 24 which through the meshing gearing 25 with the shaft I9 enables the rotation of the latter, the shaft 24 being provided with a hand actuated turning wheel or knob 26 at its lower end in convenient reach of the said operator of the vehicle so that the mirrors can be turned in unison on their horizontal arbors and in this way ing two mirrors, means for securing the mirrors for rotatable adjustment to a vehicle, said mirrors being located one above the other and the upper mirror adapted to receive the view from the rear of the vehicle, said lower mirror adapted to re. disposed shaft with a handle on the lower end ceive the object from the upper mirror. shafts and having a gear thereon meshing with the gear upon which the upper and lower mirrors'are positioned on an intermediate point of the said mounted. scars on the said shafts, a vertically coupling shaft for adjusting the mirrors simuldisposed rack having teeth meshing with said 5 .taneously.
